What causes red algae to be red?
Red algae contain red pigments called phycoerythrins, which are responsible for their characteristic red color. These pigments help the algae absorb certain wavelengths of light that penetrate deeper in the water column, allowing red algae to thrive in lower light conditions compared to green algae.
Is red or brown algae more closely related to Green algae?
Green algae are more closely related to red algae than to brown algae. Both green and red algae belong to the Archaeplastida supergroup, which includes plants and their relatives. In contrast, brown algae are part of the stramenopiles, a separate lineage. This phylogenetic distinction highlights the closer evolutionary relationship between green and red algae.

What is an adaptation of coralline algae?
Coralline algae is classed as a red algae. Red algae is unique because it has adapted to be able to photosynthesise not only in light (producing O2) but also in darkness and at night (producing CO2). This means that coralline algae can still thrive in low light, as long as the water has a high enough oxygen content.
